Abstract: Abstract of the Disclosure A bushing is provided which is arranged to be press fit into a bushing bore.  The bushing is adapted to support a high level load which is unidirectional or which changes in direction through only a small angle.          A rigid core in the bushing has a long rubber, or rubber-like, semicylinder bonded to one side of the outer sur-face thereof and has a number of uniformly spaced short rubber semicylinders bonded to the other side thereof.          The short semicylinders have a greater wall thickness than the long semicylinder so that when the bushing is pressed into the bushing bore the space between the core and the wall of the bore is practically filled on the short semicylinder side.  The long semicylinder operates in compression to support the high level load without exceeding the rubber endurance limits and therefore avoids the effects of internal deterioration in the rubber.                    -1a-

Abstract: 46,770 A HIGH PEAK POWER MICROWAVE GENERATOR               USING LIGHT ACTIVATED SWITCHES                    ABSTRACT OF THE DISCLOSURE      A high peak power microwave generator is disclosed in which a plurality of transmission lines are connected to an output wave guide at predetermined intervals along the direction of propagation.  Each transmission line is period-ically charged, and this electromagnetic energy is released into the wave guide upon the actuation of a light activated silicon switch (LASS) diode connected to the transmission line.  The LASS diodes are actuated  simultaneously by a laser beam which traverses equal optical paths to each switch.          The coincident switching of the transmission lines enables the power in each line to be additive in the wave guide, and much higher output pulses can be obtained.  Further, the high speed switching capabilities afforded by the LASS diodes means that the resulting high power can be obtained at a much higher frequency.

Abstract: ABSTRACT OF THE DISCLOSURE            A circular array of detectors is used for detecting coincident events and the point of annihilation in a positron annihilation process in a selected plane wherein the output from the detectors is processed in a computer to provide image recon-struction for the selected plane.  Bismuth germanate is shown to be more efficient than previously used detectors and the adaption of trapezoidal shape for the detectors enables more efficient utilization of the photons produced in the process. The use of absorbing metal reducing plugs between adjacent de-tectors may be used to decrease the aperture function of the detectors for low angles of incident radiation.

Abstract: NMR DISCRIMINATION APPARATUS      AND METHOD THEREFOR     Abstract of the Disclosure A method and apparatus for enhanced nuclear magnetic resonance (NMR) discrimination and detection is disclosed. In the preferred embodiment, a sample which has a first atomic element is placed in a magnetic field of a first intensity.  A reaction between the nuclei of the first atomic element and the electromagnetic field of the appara-tus produces an NMR response which is tunable with field intensity.  If the first atomic element of interest is present and intimately comingled with a second atomic element of interest, as might occur in compounds, and if the second element of interest has a nuclear quadrupolar moment and if the molecular structure conditions are proper for it to have a nuclear quadrupolar resonance (NQR), then adjust-ment of the magnetic field intensity varies the NMR fre-quency of the first element of interest to coincide with the NQR frequency of the second element of interest.  Energy is then transferred in an enhanced fashion between the nuclei of the first element of interest and the nuclei of the second element of interest.  This increased ease of transfer of energy between the two nuclei under the foregoing condi-tions reduces the NMR response time of the first element thereby improving the detectability of that element.  Imple-mentation of this effect is the basis for the reduced detec-tion time and the improved discrimination achieved in the apparatus of this invention.     A second aspect of the discrimination capabilities of the apparatus is achieved by varying the elapsed time be-tween successive observations of the NMR response of the first element of interest.  An apparatus and method allow the detection and measurement of a first element of interest in a particular compound while rejecting the NMR response from the same element located in different compounds.

Abstract: METHOD AND APPARATUS FOR NEUTRON        INDUCED GAMMA RAY LOGGING FOR DIRECT              POROSITY IDENTIFICATION            Abstract of the Disclosure In a neutron induced gamma ray well logging instrument, a neutron generator is pulsed at a clock frequency of 20 KHz.  Each neutron burst produces in-elastic scattering gamma rays which are detected during a first time interval coinciding with the neutron source being on.  Capture gamma rays are detected during a sec-ond interval subsequent to the end of each neutron burst. Upon detection of the scattered gamma rays, a detection pulse is transmitted during each of the two detection intervals.  Sync pulses are generated at a scaled down frequency rate of 200 Hz within the well logging instru-ment for transmission to the earth's surface.  The scaled-down sync pulses are applied to a phase-locked loop system for regenerating the sync pulses to the same frequency as that of the clock frequency used to pulse the neutron source and to open the detection gates in the borehole instrument. The regenerated sync pulses are then used in surface instru-mentation to route the pulse occurring during the inelastic scattering interval to one section of a multi-channel ana-lyzer.  Similarly, the pulse occurring in the capture interval is routed into another section of the multi-channel analyzer. The use of memory address decoders, subtractors and ratio circuits enables both a carbon/oxygen ratio and a hydrogen/ iron ratio to be obtained, substantially independent of chlorine content of the borehole and formation.

Abstract: ROTARY SHAFT DRIVEN REVERSE OSMOSIS METHOD AND APPARATUS     ABSTRACT OF THE DISCLOSURE             Reverse osmosis, particularly for water desalina-tion, uses semipermeable membranes which selectively permeate purified water from a feed solution pressurized by a recip-rocating feed pump driven by rotating crankshaft.  Pump action is assisted by depressurizing concentrate fluid within the pump cylinder, which has an internal displacer separating feed and concentrate fluids.  Directional valves controlling con-centrate fluid flow to and from pump cylinder are actuated mechanically by crankshaft.  A dwell interval is provided in displacer motion to permit completion of directional valve actuation while displacer is stationary and displacer rod is providing compression or decompression action to approximately equalize pressure differences across valve ports prior to valve actuation.  Detrimental concentration polarization is reduced by reducing pressure and flow fluctuations across membranes by using a differential surge absorber, a multi-feed cylinder pump in which the feed cylinders are phased apart, or a single feed cylinder pump with one or more recirculating cylinders phased equally from the feed cylin-der to supply pulses of recycled concentrate fluid.  In the multi-cylinder pumps, actuation of the piston rod of one cylinder can be used to actuate a directional valve of another cylinder, which can be a spool valve integral with displacer rod.
